Introduction To DCS
The Accessory Interface Unit
The Accessory Interface Unit, also known as the AIU, plugs into the TIU and controls any
accessory or switch wired to it. Each AIU can control up to 10 switches and 10 accessories and
features the ability to turn the accessory on or off, or activate it momentarily.
The AIU essentially acts as a large relay and simply replaces the manual switches that are
normally used to turn on and off model railroading accessories. Connection to the TIU is done
through a special cable (included with the AIU) and up to five AIUs can be daisy-chained to
one TIU.
ATTENTION: Connecting the TIU to the AIU output may cause damage to earlier
model AIU’s
